We just added a book recommender at https://12chess.com. You can open it with the new Books button in the top bar of the app, and it is also linked from the front page.

It recommends chess books to improve your tactics, strategy and endgame play, from classics like My System or Logical Chess: Move by Move to recent titles like The Woodpecker Method. Each book includes a short explanation of why we recommend it.

The books link to Amazon, and they are affiliate links: if you buy through them we get a small commission at no additional cost for you. You can also browse the current chess bestsellers on Amazon from the same page.
